The only real way to test your CDI box is to swap it out with another known good unit from the same year/make/model. Because of this, we recommend that you rule everything else out before replacing the CDI box

WE HIGHLY RECOMMEND REPLACING THE VOLTAGE REGULATOR AT THE SAME TIME AS THE CDI UNIT.
IT IS THE REASON FOR CDI FAILURES.

Before installing your new regulator/rectifier:

Check the AC output of the stator.

Replace any burned or corroded connectors on stator and regulator/rectifier

Check and repair any melted wiring.

Use hi-temp dielectric grease on all connectors.

Our CDI may use a different wire color code than your original.
All of the wires are installed in the correct order; please do not change any of the wiring configurations.
